Document Type and Number:
WIPO Patent Application WO/2013/069456
Kind Code:
A1
Abstract:
[Problem] To provide a hot water supply device and an installation structure thereof with which installation work is easily possible and high-temperature water can be efficiently obtained even in cold areas or existing buildings. [Solution] Provided is a hot water supply device (1) which supplies heated water which is obtained with a heated water circuit (4) to a usage side, comprising: a first coolant circuit (2) in which a compressor (21) which compresses a first coolant, a four-way valve (22), a first heat exchanger (11) which heat exchanges the first coolant and a heating medium, and a second heat exchanger (12) which heat exchanges the first coolant and a second coolant, are disposed; a second coolant circuit (3) in which a compressor (31) which compresses the second coolant, the second heat exchanger (12), and a third heat exchanger (13) which heat exchanges the second coolant and water, are disposed; and the heated water circuit (4) in which the third heat exchanger (13), and a fourth heat exchanger (15) which heat exchanges engine waste heat and the water, are disposed. The hot water supply device is provided with a first heating medium circuit (5) which supplies heat which the heating medium has absorbed from a heat source to the first heat exchanger (11).
